To ALL wHoM ITMAY ooNcEaN:

Be it known that I, ALLAN NEILSON, of Allegheny City, in the county of Allegheny, and State of Pennsylvania, have invented a new and improved Washing Machine; and I do hereby declare that the following is a full, clear, and exact description thereof,lwhich will enable others skilled in the art to make and u'se the same,

reference being had to the accompanying drawings, forming part of this specification, in which- Figurel represents a vertical sectional view ot' my improved washing machine.

Figure 2 is a plan or top view of the same, partly in section.

Similar letters of reference indicate like parts.

This invention relates to a washing machine in which two or more corrugated conical rollers are secured in such a manner in a swinging frame above a flexible wash-board, that their axes cross each other, while their under surfacesl are with their whole length on the said board, so that by oscillating the said frame the rollers will rotate on their larger diameters, and slip on their smaller end, and will thus at once beat and rub the clothesl to be washed.

Areprescnts a suds-box ot' usual construction, supported upon legs B B. Two upright posts, b, are arranged at its sides, and between them is pivotecl a frame, C, that is'prov'ided with a handle, D, andY can therebyreceive an oscillating motion. To theulower end of the frame C 'are secured suitable bearings for two or more corru gated conical rollers E E, which are arranged so that -the larger end of one is at the same side of the box A with the smaller ond of the next, vice versa. The under surface oi" each of these'rollcrs is perfectly level, and they are arranged in respect to each other in such amanner that their undersurfaces conform to the shape of the wash-board below. The latter is made of laths, rounded or V-shaped at their upper edge, all the laths being connected by means of strings or wires a a, as shown. The lower inner end of the board, or the last lath inside ofthe suds-box, isrmlysccured to the bottom or sides ofthe box A,or to springs which are fastened'to the box. The ends ofthe strings or wires connecting the diierent laths are there securedor are there con.

neeted with each other, and the cords or wires then passed through all the laths over vor around the `edge ofthe t box'A to a treadle, F, whereby the board G can be -more or less straightened, so as to increase the pressure upon the rollers E, more orless, as is indicated by red and black lines in g. 1. A soapbox, H, -may be connected on the outside of the strings or wires, or independent' thereof', as may -be desired.

It will be seen that this machineis of very simple construction and easily operated, and canrbe made almost wholly without metal, and altogether without springs or other weak'devices. By means of the treadle it can be operated so as to be adapted for-'washing cliiierent kinds of garments.

What I claim as new, and desire to secure by Letters Patent, is-

1. The corrugated conical rollers E, when arranged with level lower surfaces, and when secured to a. swinging frame, C, the axes oi` which rollers cross each other, substantially as-and for the purpose herein shown and described.

2. The exible wash-board G, consisting of laths, that are secured together by string'sfor wires a a,and operated by a treadle, F, substantially as set forth. i

3. The combination of the treadle F, cords a, box H, and flexible board G with each other and with the rollers E, all made and operating substantially as herein shown and described. i
